Abstract
With the rapid expansion of technology, the wireless sensor network has been spawned in recent years. Recently, Chi et al. proposed an improved energy-efficient access control scheme for wireless sensor networks based on elliptic curve cryptography. In this article, we analyze the scheme of Chi et al. and point out that their scheme cannot withstand the replay attack. To surmount the weaknesses of the Chi et al. scheme, we propose a secure energy-efficient access-control scheme for wireless sensor networks based on elliptic curve cryptography. In addition, we prove that our scheme is secure and efficient with respect to various types of attacks.
